Premiere Pro CS6 No audio from Sony AVCHD

Please help, I import AVCHD/mts from any files on my PC but there is no audio/sound, not even the audio 1 track has anything in it, the sound is simply not there??

I know FCPX needs my Sony files converting is this the case with CS6 now as cs5.5 works ok.

Thanks
